No. 8,006,397, which application claims the benefit ofpriority of U.S. Provisional Application No. 61/159,968 filed on Mar.13, 2009, all of which applications are incorporated herein by referencein their entireties for all purposes.

FIELD

This invention relates generally to leveling and positioning, and morespecifically, to systems and methods for remote leveling andpositioning.

BACKGROUND

Leveling is the positioning of a plane of an object perpendicular to thegravitational axis of the earth; whereas a plane is plumb when it isparallel to the earth's gravitational axis. For example, in a householdsetting, people typically prefer to level pictures, mirrors, and otherframed objects so that these objects are parallel to the floor, ceilingand walls of a house, which are presumed to be level themselves. In aconstruction setting, numerous structural elements must be leveled tosatisfy building codes and esthetic preferences. For example, asdiscussed above, leveling of framed objects requires that structures ofa home be themselves level, which must be done during construction.

Positioning is the placement of an object, which may include itsposition in three dimensional space, or a rotational orientation. Insome situations, positioning may include leveling. An example ofpositioning may include locating an object a certain distance fromanother object, orienting an object toward a compass point, locating theobject a certain distance from sea level or ground level, and the like.

Various devices and methods can be used to level or position an object.One exemplary leveling device is a bubble or spirit level, which is atransparent and slightly curved vial that is incompletely filled withliquid. The resultant bubble in this vial settles to the center of thevial, when the vial is level.

While this is a typical device used to level or plumb objects, it isdeficient because a user must be able to see the position of the bubblein order to properly use the instrument, and being at a distance, atcertain angles, and having an obstructed view makes bubble levelsunusable. Unfortunately, this substantially limits the use of such adevice in many settings.

Additionally, in situations where a plurality of users is leveling anobject, using a bubble level device can be cumbersome because at leastone user must read the level and relay instructions to others. This isnot efficient when an object is heavy or when it is not easy for usersto view the bubble level while working.

Such safety hazards mayinclude a beam 910 wildly swinging out of level or otherwise out ofdesired position, a hazard may include the position of moving itemsbeing dangerously close to an operator 905, and the like.

In a further embodiment, operators 905 may be able to receivepersonalized indications of leveling and/or positioning status. Forexample, presuming that the beam 910 has a first and second end X and Y,the identity of each end X and Y will be different in terms of left andright based on the perspective of the operator. The crane operator 905Cand the operator 905B near the crane 900 will perceive the X end asright, and the Y end as left. However, the ground operator 905A willperceive the Y end as right, and the X end as left. Accordingly, theleveling device assembly 100 may be operable to provide leveling orpositioning indications which can be customized to the perspective andposition of various operators 905.

FIG. 10 is a pictorial diagram of a system 1000 of interconnecteddevices, in accordance with various embodiments. The system 1000comprises a leveling device assembly 100 and a plurality of audiodevices 1020A, 1020B, and 1020C, which are operably connected via anetwork 1040. In various embodiments, the network 1040 may be a wirelessnetwork, and the leveling device assembly 100 may be connected to thenetwork 1040 via an antenna 860 (FIG. 8 c) or via a wireless networkinterface, which may be present in a portion of the leveling deviceassembly 100 and/or the leveling device 105.

As described herein, the leveling device assembly 100 may communicateposition status data, leveling data, indications relating to how toachieve a desired leveling position or position, and the like. Suchcommunications may be obtained by an audio device 1020, which maypresent such data or indications in various forms. In some embodiments,an indication relating to how to achieve a desired leveling state orposition may be presented in relation to the location of the audiodevice 1020.

For example, if an audio device 1020 is on a front side of a levelingdevice assembly 100, (i.e. a user is in front of the leveling deviceassembly 100) an indication of “move right side down” may be relevant toan observer in obtaining a level position for the leveling deviceassembly 100. However, if the audio device 1020 is behind the levelingdevice assembly 100 in the same situation, then an indication of “moveleft side down” may be relevant to an observer in obtaining a levelposition for the leveling device assembly 100.

In such examples, there may be a plurality of audio devices 1020 andindications may be modified for each audio device 1020 based on thelocation of a given audio device 1020. In some embodiments, the levelingdevice assembly 100 or audio device 1020 may modify such indicationsbased on obtained audio device location data and level location data.

Audio devices 1020 may be various devices in accordance with someembodiments. For example, a Bluetooth headset, a radio, a cellulartelephone, a personal data assistant, and the like may function as anaudio device 1020. In various embodiments, an audio device 1020 may beany device capable of producing an audio presentation.

FIG. 11 is a pictorial diagram of another system 1100 of interconnecteddevices, in accordance with various embodiments, which comprises aplurality of user devices 1130, an admin device 1110 and a levelingdevice assembly 100, which are all operably connected via a network1040. Additionally, each user device 1130 is operably connected to anaudio device 1020.

As discussed in relation to FIG. 10, various devices may be operablyconnected via a wireless network 1040, and may be connected in variousother ways. In some embodiments, a user device 1130 and audio device1020 may be embodied together in a helmet, an earpiece, a cellulartelephone, a personal data assistant, and the like. Additionally, asdiscussed above, a determination may be made regarding location of anyof an admin device 1110, user device 1130, and audio device 1020, andindications relating to how to achieve a desired leveling status orposition, and the like, may be modified or customized based on such adetermined location of various devices.

In further embodiments, a determination of a danger zone may be made inrelation to objects associated with a leveling device assembly 100,which may include objects being leveled or positioned by the levelingdevice assembly 100. For example, a danger zone may be defined as anarea where an object would fall if it were to be released from acoupling, lose balance, fall down a slope, explode, and the like.

In such embodiments, a danger zone may be determined for an objectassociated with a leveling device assembly 100, and a furtherdetermination may be made whether a given device is located within thedefined danger zone. Where a user device 1130 is located in a defineddanger zone, an alert may be presented via an audio device 1020, aleveling light 325 or laser 315 (FIG. 3), a speaker, and the like. Insome embodiments, such an alert can be provided to a plurality of userdevices 1130, wherein some are within the danger zone or such an alertmay only be provided to user devices 1130 within the danger zone.

In various embodiments, the admin device 1110 may record a leveling orpositioning session, which may include data regarding level position,leveling status, danger zone, position of one or more user device 1130,position of one or more audio device 1020, position of an admin device1110, and the like. In other embodiments, such data may be recorded byany of a leveling device assembly 100, an admin device 1110, a userdevice 1130, an audio device 1020, and the like. In further embodiments,and admin device 1110 may obtain an alert, position data, level-statusdata, define a leveling goal, define a positioning goal, define dangerzone parameters, and the like.

In various embodiments, wherein indications relating to achieving adesired leveling status or position are obtained wirelessly, via anaudio presentation, or via a visual presentation, such embodiments maybe desirable because a leveling device assembly 100 may not beimmediately visible to one or more users because of where the levelingdevice assembly 100 is position on an objected being leveled orpositioned.

For example, a user of a leveling device assembly 100, having only aliquid and bubble leveling body 110, may not be able to view such arelatively small indicator when leveling a post with a tractor orbackhoe. In such an example, it may be desirable to obtain indicationsof position and level status which can be perceived from a distance orthat can be perceived in noisy environments. Here, it may be desirablefor the user to be able to view or hear such indications while drivingthe tractor or backhoe.

In various embodiments, there may be a plurality of level deviceassemblies 100 connected via a network 1040, which may each communicatedata regarding position status or level status to each other, to amaster leveling device assembly 100, to an admin device 1110, to a userdevice 1130, an audio device 1020, and the like. In such embodiments,there may be more than one leveling and/or positioning goal, andindications may be given to facilitate each leveling device assembly 100in reaching its leveling and/or positioning goal.

FIG. 13 is a diagram illustrating the actions taken by a leveling device100 and an audio device 1020 in accordance with various embodiments. Theactions begin where a level goal is defined 1305. In some embodiments, adefault leveling goal may be true level, whereas other leveling goals inrelation to true level may be defined 1305.

Level status is determined 1310, and a level status alert is formatted1315 and the level status alert is sent 1320 to the audio device 1020,where the level status alert is presented 1325. For example, a presented1325 status alert may be “rotate clockwise ten degrees”; “move rightside down”; “level goal achieved”; and the like. In further embodiments,level status alert may be formatted 1315 based on a determined locationof an audio device 1020 or other device.

FIG. 14 is a flow diagram illustrating a leveling routine 1400 inaccordance with various embodiments. The leveling routine 1400 begins inblock 1405 where a level goal is defined, which may be defined via aninput on the leveling device assembly 100, or remotely via a user device1130 or admin device 1110. In further embodiments, a default level goalmay be automatically defined as true level.

In block 1410, a level status is determined, which may include degreesor percentage off from level, and the like. In block 1415 a level statusalert is formatted and in block 1420 a level status alert is sent 1420.A level status alert may be sent to another device, to a leveling light120, a speaker 140, and the like.

In decision block 1425 a determination is made whether the levelingsession has ended, and if the leveling session has ended the levelingroutine 1400 ends in block 1499. However, if the leveling session is notended, then the leveling routine 1400 cycles back to block 1410, wherelevel status is again determined.

FIG. 15 is a diagram illustrating the actions taken by a leveling device100 and an audio device 1020 in accordance with various embodiments. Theactions begin where a goal position is defined 1505, and then positionstatus is determined 1510, a position status alert is formatted 1515 andthe position status alert is sent 1520 to the audio device 1020 wherethe position status alert is presented 1530.

In some embodiments a positioning goal may comprise a compass directionor GPS coordinate or be in relation thereto, and may be defined by aninput device on the leveling device assembly 100 or be defined by a userdevice 1130 or an admin device 1110. Additionally, in variousembodiments, the position alert may be formatted 1515 based on anobtained location or position of a user device 1130, admin device 1110,or audio device 1020.

FIG. 16 is a flow diagram illustrating a positioning routine 1600 inaccordance with various embodiments. The positioning routine 1600 beginsin block 1605 where a positioning goal is defined, which may be definedvia an input on the leveling device assembly 100, or remotely via a userdevice 1130 or admin device 1110. In further embodiments, a defaultpositioning goal may be automatically defined as true level or tocomprise true level.

In block 1610, a position status is determined, which may includedegrees or percentage off from level, a GPS coordinate, a distance, andthe like. In block 1615 a position status alert is formatted and inblock 1620 a position status alert is sent 1620.

In decision block 1625 a determination is made whether the positioningsession has ended, and if the positioning session has ended thepositioning routine 1600 ends in block 1699. However, if the positioningsession is not ended, then the positioning routine 1600 cycles back toblock 1610, where position status is again determined. In variousembodiments, a positioning session may end when indicated by a user.

FIG. 17 is a diagram illustrating the actions taken by a leveling device100 and a user device 1130 in accordance with various embodiments. Theactions begin where danger positions are determined 1705. A levelingdevice assembly 100 may be associated with various objects and suchobjects may have characteristics that make them dangerous, such asexplosive, crushing, corrosive, and like properties. For example, alarge sculpture being installed may need to be leveled, but may create arisk for users leveling and installing the sculpture, because it mayfall and crush such a user. Accordingly, in such a situation, a dangerzone may be defined as a radius or area around the sculpture, which maytake into account center of gravity, height, weight, and the like. Sucha defining may be automated or may be defined by a user.

Returning to the actions, the user device 1130 determines 1710 theposition of the user device 1130, and the user device position is sent1715 to the leveling device assembly 100, where a determination 1720 ismade whether the device position is equal to a danger position orwhether the device position is within a danger zone or area. A dangerposition alert is formatted 1725 and sent 1730 to the user device 1130,where the danger position alert is presented 1735.

In various embodiments, there may be a plurality of user devices 1130and each user device 1130 may be sent 1730 the same danger positionalert or a danger position alert may be custom formatted 1725 and sent1730 each user device 1130 based on user device location and identity.For example, if a first user device 1130A is in a danger zone, the firstuser device 1130A may be sent 1730 a danger position alert such as “UserDevice A, you are in a danger zone!”; however, a second user device1130B may not be sent 1730 a danger position alert or may be sent adanger position alert such as “Use device A is in a danger zone!”Accordingly, devices may be alerted to their own danger, to the dangerof other devices, and the like.

FIG. 18 is a flow diagram illustrating a device danger alert routine1800 in accordance with various embodiments. The device danger alertroutine 1800 begins in block 1805 where danger positions are determined,and in block 1810, a user device position is obtained.

In decision block 1815 a determination is made whether the user device1130 is in a danger position. In various embodiments, such adetermination may be made by comparing the obtained user device positionto the defined danger positions. If the user device 1130 is not in adanger position the device danger alert routine 1800 continues to block1830, where a determination is made whether the danger position alertsession has ended. However, if the user device 1130 is in a dangerposition, then the device danger alert routine 1800 continues to block1820, where a danger position alert is formatted. In block 1825 thedanger alert is sent to the user device 1130.

In decision block 1830 a determination is made whether the dangerposition alert session has ended, and if so, the device danger alertroutine 1800 is done in block 1899. However, if the danger positionalert session is not ended, then the device danger alert routine 1800cycles back to block 1805, where danger positions are again determined.

For example, in various embodiments, danger positions and user devicepositions can be continually determined and/or obtained. Dangerpositions may change as an object associated with the leveling deviceassembly 100 changes positions, or as the object associated with theleveling device assembly 100 changes level status. When it is determinedthat the user device 1130 is in a danger position, an alert can beformatted and sent to the user device 1130 so as to warn a user. Thiscan be done continually in real time or at defined intervals during adanger position alert session.

The following FIGS. 19, 20 and 21 depict various embodiments of levelingdevice assembly 100 networks, and uses thereof. In such embodiments, anetwork of leveling device assemblies 100 may be networked via awireless network, and may also be connected to various other devices orservers via a wireless network, the internet, or the like.

FIG. 19 depicts a plurality of leveling device assemblies 100 positionedat various intervals along both sides of a road. Adjacent levelingdevices form a plurality of triangular motion planes 1950, which may beused to model the movement of portions of the road and ground withineach plane 1950 and which collectively form a matrix 1900. For example,motion plane 1950 ₁ is defined by imaginary lines connecting levelingdevice assemblies 100 ₁, 100 ₆, and 100 ₇. Motion plane 1950 ₂ isdefined by imaginary lines connecting leveling device assemblies 100 ₁,100 ₂, and 100 ₇.

Each leveling device assembly 100 may obtain positioning and level data,which may be used to model movement of each motion plane within thematrix 1900 and thereby model movement of the road and ground as awhole. Additionally data such as accelerometer data, and temperaturedata may also be obtained.

In an embodiment, data collected or modeled from a matrix 1900 can bepresented to various users. For example, road signs may present imagesthat reflect road conditions in real time, which may be based on dataobtained from the matrix 1900. Additionally, such data collected fromthe matrix 1900 can be used by transportation agencies to determine whena road surface may need immediate repair or future repair.

Similarly, FIG. 20 depicts a matrix 2000 comprising a plurality ofleveling device assemblies 100, which also forms a plurality of motionplanes (not labeled). As shown in FIG. 20, the leveling deviceassemblies 100 are positioned in various locations on a mountain range,and the motion planes may be various shapes and sizes.

Accordingly, in an acute seismic event, or over time, the pitch and yawlof each plane may reveal a relationship between planes that may nototherwise be observable with other types of point measurement. A matrix2000 as in FIG. 20 may be applied to locations with seismic activity toreveal shadows of tectonic interaction and movement that may nototherwise be observable by other seismic systems. Such measurements andmodeling may be useful in the prediction of acute seismic events such asearthquakes.

In embodiments where leveling device assemblies 100 are positioned inand about the ground or ground features, a leveling device assembly 100may housed within a hollow cylinder oriented perpendicular to the groundor the gravitational axis. Such cylinders may house the leveling deviceassembly 100 at, above, or below grade.

FIG. 21 depicts a plurality of leveling device assemblies 100 positionedat various points on a bridge. Here, each leveling device assembly 100may provide positioning, leveling, seismic, and acceleration data, whichmay be associated or attributed to a portion, part or plane of thebridge on which the leveling device assembly 100 is positioned.

Accordingly, based on data obtained from the leveling device assemblies100, modeling of the movement, strain, and position of the bridge may beachieved in various embodiments. For example, various parts of thebridge may be identified as being high or low strain areas, which may becorrelated with traffic volume, or temperature changes. Such modelingmay be used to determine areas or parts of the bridge that are in needof repair, or that need to be reinforced to prevent damage orcatastrophic failure of the structure. In further embodiments, such anetwork of leveling device assemblies 100 may be applied to variousstructures.

FIGS. 22 a and 22 b are a side view of a positioning sphere 2200 inaccordance with various embodiments. FIG. 22 a depicts the positioningsphere 2200 in a level position, and FIG. 22 b depicts the positioningsphere in a non-level position. The positioning sphere 2200 comprises adata ball 2210, which is suspended in a suspension media 2230 andcontained within a shell 2225. The data ball 2210 may rotate freelywithin the suspension media 2230 and shell 2225. Additionally, the shell2225 is coupled to a leveling plate 2235, which is an extendedsubstantially flat member.

In some embodiments, the surface of the data ball 2210 is encoded withdata, which relates to a position on the data ball 2210. For example,the surface of the data ball 2210 may be encoded with data like acompact disc (“CD”), digital versatile disc (“DVD”), BlueRay disc, andthe like, which can be read by the laser 2255 of a reader 2250.Accordingly, as the data ball 2210 rotates within the suspension media2230, the change in position can be tracked as the reader 2250 reads thedata that passes in view of the laser 2255.

In some embodiments, the data ball 2210 comprises a gravity body 2245,which is a body that is heavier than other portions of the data ball2210 and therefore the gravity body 2245 is attracted to the earth'sgravitational center via a gravitational force 2265. Accordingly, avertical plane 2215 of the data ball 2210 is kept in alignment with theearth's gravitational center despite movement of the shell 2225 orstructures attached thereto such as the leveling plate 2235.

In further embodiments the data ball 2210 comprises a compass body 2240,which is a magnetized body that is attracted to the earth's polar north.Accordingly, the compass body 2240 will be attracted to polar north viamagnetic forces 2260 and a plane of the data ball 2210 will be alignedalong a horizontal axis 2220 to magnetic north despite any change inposition of the shell 2225 and structures attached thereto such as theleveling plate 2235.

FIG. 22 a depicts the positioning sphere 2200 in a level position asindicated by the leveling plate 2235 being parallel to depictedhorizontal axis 2220, and FIG. 22 b depicts the positioning sphere in anon-level position, as indicated by the leveling plate 2235 not beingparallel to depicted horizontal axis 2220. However, despite the levelingplate 2235 and shell 2225 being in a different position, the data ball2210 retains the same orientation and alignment because the gravity body2245 remains attracted to the earth's gravitational center viagravitational forces 2265, and the compass body 2240 remains orientedtoward magnetic north via magnetic forces 2260.

In various embodiments, the position on the data ball 2210 being read inFIG. 22 a by the reader 2250 may be considered a desired or zeroposition because the leveling plate 2235 is level, and the compass body2240 naturally orients the data ball 2210 toward magnetic north.Accordingly, any changes in position from such a desired state may betracked as the data ball 2210 rotates in relation to the reader 2250.

In some embodiments, the desired position may be changed. For example, aposition wherein the leveling plate 2235 is perpendicular to level orany other orientation may be defined as a desired position or zeroposition.

FIG. 24 shows a perspective view of a leveling device assembly 100K inaccordance with an embodiment. The leveling device assembly 100Kcomprises housing 2400, which may comprise a first, second, third andfourth face 2405, 2410, 2415, 2420. The first face 2405 may include anelongated sloped trench 2425, which extends from a first end 2445 to asecond end 2450. The second and third faces 2410, 2415 may comprise anelongated coupling slot 2435A, 2435B respectively. The fourth face 2420may include an angular notch 2430 that extends from the first end 2445to the second end 2450. The housing 2400 may comprise one or more devicecavity 2440A, 2440B.

In an embodiment, the housing 2400 may have a substantially cuboidprofile aside from features such as the sloped trench 2425, angularnotch 2430 and one or more coupling slot 2435A, 2435B. For example thefirst, second, third and fourth face 2405, 2410, 2415, 2420 and firstand second end 2445, 2450 may have a substantially rectangular profile,and where the first, second, third and fourth face 2405, 2410, 2415,2420 and first and second end 2445, 2450 are square to other and meet ata right angle. Such a configuration may be desirable in an embodimentbecause it makes each side of the leveling device assembly 100K operableto engage a planar surface so that the level status of the planarsurface may be detected and indicated by the leveling device assembly100K.

Additionally, in an embodiment, it may be desirable to detect the levelstatus of objects that are non-planar, or to detect the level status ofcorners, or the like. Accordingly, in an embodiment, sloped trench 2425and angular notch 2430 may make the leveling device assembly 100Koperable to engage non-planar objects or features.

For example, the sloped trench 2425 may be configured to engage varioussizes of cylindrical objects. The sloped trench 2425 may be uniformalong its length extending from the first end 2445 to the second end2450 and being aligned with a central axis of the first face 2405.

In an embodiment, the curve of the sloped trench 2425 may be a Witch ofAgnesi curve having the Cartesian equation y(x²+a²)=a³ or the parametricequation of x=at, y=a/(1+t²). The Witch of Agnesi curve may be desirablein some embodiments because it may provide stability when coupled withcylindrical objects, while providing the ability to couple withcylindrical, ovoid, or curved objects having a wide range of diameters.Although the Witch of Agnesi curve may be desirable in some embodiments,any other suitable curve or substantially curved profile may be employedin other embodiments.

The angular notch 2430 may be configured to engage angular objects andsurfaces, such as a corner where planar faces meet. The angular notch2430 may be uniform along its length extending from the first end 2445to the second end 2450 and being aligned with a central axis of thefourth face 2420. In one embodiment, a notch central apex 2431 maydefine a 90° angle.

In some embodiments the angular notch 2430 and sloped trench 2425 may beon opposing faces of the housing 2400. Additionally, the angular notch2430 and sloped trench 2425 may also be aligned in a similar plane. Forexample, a trench central apex 2426 of the sloped trench 2425 may bealigned with the notch central apex 2431 in a common location. In someembodiments, the angular notch 2430 and sloped trench 2425 may not bealigned or may not be on opposing faces.

One or more coupling slot 2435A, 2425B may be located on one or moreface 2405, 2410, 2415, 2420. In an embodiment, coupling slots 2435A,2435B may be an elongated slot that extends from the first end 2445 tothe second end 2450. The coupling slots 2435A, 2425B may comprise a slotopening-passage 2436 and a slot inner-cavity 2437.

The slot opening-passage 2436 may be narrower than the slot inner-cavity2437. For example, as depicted in FIG. 24, the slot opening-passage 2436may be a substantially uniform rectangular opening, which extendsinwardly and opens up into the slot inner-cavity 2437, which may bewider than the slot opening-passage 2436.

The leveling device assembly 100K may further include a coupling pin2455A, which is configured to couple with the housing 2400 via couplingslots 2435A, 2425B. The coupling pin 2455A may comprise a coupling-pinhead 2456, a coupling-pin shaft 2457, and a coupling-pin bow 2458. In anembodiment, the coupling-pin head 2456 is configured pass within theslot opening-passage 2436 in a first orientation and configured tocouple within the slot inner-cavity 2437 in a second orientation. Thecoupling pin 2455A may be inoperable to pass within the slotopening-passage 2436 in the second orientation.

For example, the coupling-pin head 2456 may have a length thatcorresponds to the height of the slot inner-cavity 2437, and thecoupling-pin head 2456 may have a width that corresponds to the heightof the opening-passage 2436. When inserting the coupling pin 2455A intothe slot opening-passage 2436 the coupling-pin head 2456 may be orientedsuch that the coupling-pin head 2456 may slide within the slotopening-passage 2436 and into the slot inner-cavity 2437. The couplingpin 2455A may then be rotated (e.g., 90°) such that the lengthcoupling-pin head 2456 turns to engage the slot inner-cavity 2437. Thecoupling pin 2455A may thereby be coupled or held within a coupling slot2435A, 2425B.

In an embodiment, the coupling of one or more coupling pin 2455A withinone or more coupling slots 2435A, 2425B may facilitate the levelingdevice assembly 100K being secured to or coupled with various objects.For example, a first and second coupling pin 2455A may be coupled onopposing faces of the housing 2400 via coupling slots 2435A, 2425B, andan elastic band may extend between the first and second coupling pin2455A. The elastic band may extended around various object (e.g., pipes,beams, or the like), such that the leveling device assembly 100K can becoupled or held thereto.

In other embodiments, a coupling pin 2455A may include additionalfeatures or structures, which provide for coupling of the levelingdevice assembly 100K to various objects. For example, FIGS. 25 a, 25 band 25 c depict embodiments of a coupling pin 2455B, 2455C and theleveling device assembly 100K of FIG. 24. For example, FIG. 25 b depictsan embodiment of a coupling pin 2455B, which includes an extendedcoupling arm 2458. FIG. 25 a depicts a first and second coupling pin2455B coupled within coupling slots 2435A, 2425B (FIG. 24). The couplingarms 2458 of the first and second coupling pin 2455B may be operable toattach to various objects, such as a pipe, or the like.

In another embodiment, as depicted in FIG. 25 c, the housing 2400 may beheld against a surface by a suction coupling pin 2455C. The suctioncoupling pin 2455C may comprise a suction arm 2510, a suction cup 2520,and a soft shoe 2530 at a distal end of the suction arm 2510. Forexample, the suction coupling pin 2455C may be operable to couple with asurface such as glass, and allow the housing 2400 to be held thereto.

The housing 2400 may define one or more one or more device cavity 2440A,24408. For example, FIG. 24 depicts a first and second device cavity2440A, 2440B, which extend from the first end 2445 to the second end2450. In some embodiments, one or more first and second device cavity2440A, 2440B may house a portion of a leveling device (not shown in FIG.24), which may have any suitable components, features, abilities, or acombination thereof, as described herein in one or more embodiments. Forexample, a leveling device 105 disposed within a cavity 2440 of thehousing 2400 (as shown in FIG. 25 d) may comprise various leveling,positioning, and acceleration functionalities. A leveling device 105disposed within the housing 2400 may comprise elements such as acompass, a leveling body, a global positioning system (GPS), anaccelerometer, an electronic timing device, a compass device, anazimuth-finding device, a vector detecting device, image capturingdevice, audio recording device, and the like. However, in someembodiments, a leveling device 105 may lack one or more of thesefunctionalities and related functional elements, and may merely be aprocessor or computer.

The housing 2400 may also be magnetic. For example, the housing maycomprise a magnetic portion 2488 on any of the faces 2405, 2410, 2415,2420 or ends 2445, 2450. In an embodiment, the housing 2400 may comprisea plurality of magnetic strips 2488 that may be oriented parallel orperpendicular to the axies of faces 2405, 2410, 2415, 2420 or ends 2445,2450. In one embodiment, a plurality of magnetic strips 2488 may bedisposed on the first face 2405, which at least extend from the secondface 2410 to the third face 2415 and parallel to the first and secondend 2445, 2450.

In some embodiments, corners where faces 2405, 2410, 2415, 2420 or ends2445, 2450 meet may be rounded or truncated. For example, such a cornermay be flatly, convexly, or concavely truncated. Such an embodiment maybe desirable because it may allow the housing 2400 to be adaptable toengage with a wider variety of surfaces and object contours.

In some embodiments (e.g., FIGS. 25 e and 25 f), caps 2460A, 2460B maybe operable to cover and engage with the ends 2445, 2450. Such caps2460A, 2460B may include an extension of coupling slots 2435A, 2535B andmy also conform to the profile of the ends 2445, 2450. In an embodiment,caps 2460A, 2460B on the ends 2445, 2450 may provide a water-tight orair-tight seal between the device cavities 2440A, 2440B and the externalenvironment. In an embodiment, caps on the ends 2445, 2450 may support avacuum or positive pressure within the device cavities 2440A, 2440B withrespect to the outside environment.
